Simple Straight Line Timeline

So it looks like I didn't actually hit the "Post" button on Friday to your similar question.

Here's what I had saved as a draft:

I tried setting up something similar to your mockup using basic visuals, and got close, but man is it obnoxious to customize it into a super basic timeline like you want. I could get it either to show all events in one clean view, or I could have them spaced relative to each other with a lot of extra dates being shown.

As far as custom visuals, I found that Sparkline by OKViz seemed to work the best and have the most options, but I couldn't find a way to show dates without hovering.

Here's a sample of what I was able to come up with: https://drive.google.com/open?id=1KgkC5iAynorlu0xmHh7GG1efC6dGNH69

Honestly, if you have the time, I would look into creating a custom visual for this.  It should be dead simple, and if you can get it uploaded on the marketplace, I'm sure tons of people would use it.
